To all whom it may concerm.

Be it known that I, NICHOLAS SEIBERT, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in OilFeeders for Steam- Valves, of which the following is adescription.

My invention relates to that class of oil feeders commonly called "displacen1ent-lubricators, wherein the water of condensation is fed into the oil containedin a reservoir and by its own gravity sinks to the bottom, displacing an equal amount of oil.

Heretofore it has been very difficult to oil uniformly the valves and pistons of locomotive-cylinders, for the reason that the cylinders are'subject to many changes of steam-pressu re, and these changes being communicated to the oil-feeders through the oil-pipes; hence the oiling is not uniformeither too much or not enough. a

My invention is designed to' overcome this difficulty; and it consistsnearly of one casting, to avoid leakage and also to cheapen to the purchaser.

In the accompanying drawings, in which similar letters of reference indicate like parts,

Figure 1 represents a vertical section through oil-feeder; Fig. 2, a horizontal section .on line x 00 of Fig. I. Fig. 3 represents crosssection of oil-feeder; Fig. 4, ahorizontal section online 00 m of Fig. 3; Fig. 5, a sleeve detail of cross section, Fig. 3; Fig. 6, a detail showing front view of sight-feed of section, Fig. 1.

'Qis the oil-reservoir; P P, plug; R R R, water-chamber; L L, feed-valve; H H H, solid part or lip over which the feed-water passes in the sight-feed; NNN, nut; Z Z Z, water passage; K K, glass; D D, oil-tube; Y Y, two-way plug-cock; S S, large passage; TT, small pas sage, about one-sixteenth of an inch; U U, oilpipe leading to the valvechest; \V \V, nut; 'V V V, iron to fasten oil-feeder to boiler; B, oil-passage into steam-equalizing chamber; 0 O O O O, equalizingchamber; A A, oil and steam passage leading to the valve-chest; J J, water draw'ofl valve; M M, steam-pipe from boiler; GGG, sleeve; E E, steam-passage; F F F, annular steam-passage; I, steampassage; C, steam-passage. The oil-feeders are placed one on each side of the boiler in the cab, and pipeU connected with the oil-pipes now in use.

on each side is on a level with the top of the boiler.

The operation of my invention is as follows: Plug P is removed, and reservoir Q is filled with oil or other lubricant, steam is let into pipe M, the two-way plugcock is turned so' that the small passage T will com um nicate with the steam-equalizing chamber 0 O. The feed valve L is now set so as to feed as much water as oil may be required on the valves and pistons, which can be observed through the glass K, the water flowing into the oil by its own gravity, and thereby an equal amount of oil is being expelled through tube D into the steamequalizing chamber, steam coming from the boiler through pipe M, and into sleeve G, and out at E, into the annular steam-passage F, and down through steam-passages I and C, as indicated by the arrows, into the stcanrequalizing chamber, then meeting the oil coming through passage B, and mixing with the steam, is forced out by the steam through passages A and T into pipe U, and upon the valves and pistons.

The object of the sleeve G is to prevent the water of condensation in pipe M from passing down into steanrpassage I, and causing the water to flow through sleeve (3- into the waterchamber R R R.

The object of the steai'n-equalizing chamber is to have an equal pressure of steam therein as that contained in the boiler when the steam is shut off from the cylinders or engines. It cannot disturb the oil-feed, because the oilaud steam passages A and T are so small, particularly the passage T, in the two-way plug-cock, that it does not diminish the pressure of steam in the equalizing-chamber, for the reason that the supply is so much greater than the small amount of steam going out with the oil. Ifound by actual experiment that the steam-pressure in the boiler when the engines were working was from ten to twenty per cent. greater than the returning steam-pressure in the oil-pipes near the oil-feeders; hence I utilize this superior pressure to blow or force the lubricant against the returning steam-pressure in the oil-pipes, and thence to the valves and pistons.

Another object is to oil one or more engines from one equalizingchaniber, and also that either oil or tallow may be used in cold weather.

The object of the large passage in the two- Way plug-cock is to enable the engineer to blow out any large pieces of dirt which may find their wayinto the equalizing-chamber by turning the passage S to communicate with that of the chamber.

The object of the small passage is to retain a constant boiler-pressure in the equalizing chamber, in order to have a uniform oil-feed 7 under all conditions of steam-pressure in the of a sleeve, G, with the opening E, and placed in the steam-passage I, so as to form an annular steani-passage surrounding said sleeve, the steampassages I C, and steam-chamber O O, and reduced outlet A, for the purposes as set forth, substantially as described.

2. In combination with acylinder oil-feeder, a two-way plug-cock with its passages T S, for the purposes as set forth, substantially as described.

3. The combination, in a cylinder oil-feeder adapted to feed a steady supply of oil, the steam-passages I O,steam-chamber O O,and reduced outlet A, so constructed as to retard the outgoing steam and oil, for the purposes as set forth, substantially as described.
